I figure that I could mod the I/O bracket, but then there's the problem of getting the cooler to be one-slot. I thought about watercooling, but unfortunately, the card uses a non-reference pcb, which means that finding a waterblock for it would be practically impossible.

So, here's my challenge for the people of OCN: Find A- A single-slot 770 that I can use a waterblock on (reference pcb or otherwise), or B- A waterblock for the Galaxy card.

As a side note, is it possible to mod a card like the reference 770 by cutting off the top DVI connector to make it a one-slot card? If so, how risky is the procedure?

Just use a generic waterblock and heatsinks on the chips. The actual chips are the same, only their location changes. It's also cheaper btw. I don't really understand why people always go for the full coverage blocks. It seems like a waste of money to me.

if you're going to stack them close, and it sounds like you are, it would help to have a big side fan on your case blowing at them, but that's not undoable.

I know that full cover blocks aren't necessarily cost effective, however, I really enjoy the aesthetics of them. I suppose it's not important to some people, but I have the time and money to spare on making my system look as good as I want it to.

if you got 3 GPUs single stacked though would anyone even be able to see them? They make some very pretty all copper heatsinks and blocks.

Copper also has some interesting color options. You can treat it with various chemicals and hit it with a torch and it will turn colors.

the most common is a brown black with is done with urea. (this is why it's so common. You literally just pee on it, though you can buy pure urea too)

You could even engrave them if you want, or patina THEN engrave for bright shiny copper under the patina. Thing is I suspect it's your only option. If they don't make one you can buy a generic, or have one made.
